Compare any two graphics cards:
GeForce GT 240 GDDR5 vs GeForce GTX 470
IntroThe GeForce GT 240 GDDR5 comes with a GPU core clock speed of 550 MHz, and the 512 MB of GDDR5 RAM runs at 850 MHz through a 128-bit bus. It also features 96 Stream Processors, 32 TAUs, and 8 Raster Operation Units.Compare those specifications to the GeForce GTX 470, which has a GPU core clock speed of 607 MHz, and 1280 MB of GDDR5 memory running at 837 MHz through a 320-bit bus. It also is made up of 448 SPUs, 56 TAUs, and 40 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 470 should perform much faster than the GeForce GT 240 GDDR5 overall. (explain)
Texel RateThe GeForce GTX 470 is a lot (about 93%) better at texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 470 is the winner, by a large margin. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
